Higher level management in the translation provider
The level of proficiency may be measured, for example by local education tests, internationally recognised examination schemes or organisation internal testing.
However, in the case of the translation consumer it is often not feasible to have more than an informal notion of the degree of his proficiency in the source language.
The degree to which this characteristic is pertinent in a specific evaluation will depend on what the translation consumer will do with the translation delivered to him. For example, whether he will in some way repair or polish it.
